Epoxy (Ni+Cu+Ni+BE)
Epoxy coated magnets have excellent resistance to moisture, humidity and submersion. We are often contacted by customers looking for a magnetic solution for outdoor applications. The standard Nickel coated Neodymium magnets are not well equipped to withstand humid conditions. The Nickel coating will eventually succumb to the elements and the magnetic material will corrode.

Epoxy (Ni+Cu+Ni+BE)
Epoxy magnets are well suited to humid atmospheric conditions. However it is important to note that if the epoxy coating is scratched then the protective layer will be breached. For this reason it is important that epoxy magnets are handled with care. It is advised that customers refrain from handling and repositioning the magnet more than necessary.
Harsh environments with humid conditions can be problematic for many Neodymium magnetic products. Seaside locations and constant exposure to weather can be the cause of magnets failing. It's important to select a coating that can overcome these conditions to ensure your magnet is able to perform reliably.
Other forms of magnets including Ferrite or Samarium Cobalt are also viable alternatives in these types of situations. They are resistant to corrosion and can withstand humid environments. These traditional forms of magnets lack the super magnetic power of Neodymium. They require a larger size of magnet to achieve a similar holding strength.
Epoxy coated magnets are generally black and glossy in appearance however white gloss is also available. Epoxy coated Neodymium magnets can be glued into position using magnet rated glue. Â One of the main industries that regularly use epoxy magnets is the marine industry. These include fishing operators, sightseeing vessels, public marinas, transport ferries and cruise ships. Magnets are used in a myriad of ways to store and secure items in and around boats and ships. There are a number of different magnetic coatings available and choosing the best coating for your application is important. To determine the ideal coating consider factors such as the environment, the durability required, temperature and appearance. There is a helpful guide to the full range of coatings available on our Knowledge Base page. The super smooth Teflon surface slides easily, allowing for easy repositioning. Teflon coatings also provide enhanced water resistance compared to other coatings.
Uses for Epoxy Magnets
Magnets are able to hold suspended items or secure items on a vertical surface or floor. A significant portion of water vessels are made of steel and there are plenty of opportunities for magnets to be employed.
Motors, sensors and automotive devices also incorporate epoxy coated magnets. They are able to withstand moisture that these applications may encounter.
Choosing the best coating
Neodymium magnets are available in a range of coatings that are suited to different situations and environments. Teflon, Plastic, Gold and Zinc are some of the options available. In applications where friction is an issue then Teflon is a fantastic coating. Electronic or mechanical operations often require this attribute.
